The problem

Is your business running on too many disconnected systems?

Most small businesses run on a patchwork of tools that don't talk to each other. Every gap costs time, money and customers.

QuickBooks for the booksExcel for everything elseA scheduling appA separate CRMWhatsApp with employeesPaper notesAnother inventory system

Leads slip through the cracks

Inquiries sit in texts, emails and notebooks, and follow-ups get forgotten.

The same customer, typed in five times

Every app wants its own copy of your data, and none of them match.

No clear view of profit

Sales, expenses and payroll live in different places, so you're never sure where you stand.

Your team works blind

Employees can't see schedules, jobs or stock without asking you.

BusinessOS brings the whole operation into one place.

Start here · How it works

Live in three steps

No IT team, no setup fees, no complicated configuration.

Install it once

Install BusinessOS on one computer, your host. Pick your industry in a quick setup wizard and it tailors itself to your business.

Add your info

Enter your clients, staff, products and services. Everything you type is saved locally on your device, instantly and privately.

Connect & run everything

Point your other computers at the host, with nothing to install on them, and invoice, book, check out and report from any screen. No internet needed.

Early customers

Businesses already running on BusinessOS

Three of the first companies to put their whole operation on one system they own.

★★★★★
"We were tracking leads in a spreadsheet and deals in my head. BusinessOS put our clients, follow-ups and numbers in one place, and it runs on our own machines with no monthly fee."
Manuel M. · New SpringsReal estate & investment
★★★★★
"Between job costs, invoices and crew hours, nothing lined up. Now the whole build is in one system, and my team sees the same information I do without calling me."
Jennifer L. · J&L Vision HomesHome construction
★★★★★
"Quotes, orders and invoices used to live in three places. BusinessOS runs our jobs from quote to payment, and we paid once instead of renting more software."

One install · Windows · shared workspace

Install once.
Work from the same information.

Install on one computer. Every other computer, phone and tablet in the building connects to it over your own local network, with nothing to install and nothing to set up per desk.

Host it on Windows

Install once on any Windows PC or laptop and it becomes the host for your whole business. No browser tabs, no monthly cloud fees, no waiting on the internet.

One-click installRuns offlineFull feature set

One host computer. Real-time for everyone.

The host holds your data. Every other computer, phone and tablet connects over the network you already have, with nothing to install, and every sale, invoice, booking and stock change appears on every screen the moment it happens.

Works on every screen

Use it on computers, phones and tablets.

Install BusinessOS once on a Windows computer. Everyone else opens it in their web browser on your office Wi-Fi.

Computers

Front desk, office and back office, all on the same data.

Phones

Check schedules, clients and sales from the floor.

Tablets

Check-ins, POS and sign-offs at the counter.

Nothing to install on phones or tablets. Just open the browser while connected to your business network. The main computer runs on Windows 10 or 11.

"The software you run your business on should be fast, private, and entirely yours, not a subscription that watches over your shoulder."
The principle behind BusinessOS
All-in-one small business software

Everything your business runs on, in one place

Six areas, 40+ tools, one system. Pick your industry at setup and BusinessOS shows the tools you use and hides the rest, so nothing gets in your way.

Also included · AI Assistant

An assistant that actually knows your software

This isn't a generic chatbot bolted onto a help page. The BusinessOS Assistant understands the platform itself, so it can answer, guide, and then take you straight to the right screen to get it done.

Private by design: the Assistant runs on your computer and never sends your business records to us or any outside AI service.

Answers every question

Ask about any feature and get a clear answer in plain language.

Guides you step by step

Walks you through the task in order, not a wall of documentation.

Takes you to the right page

One tap and you're on the exact tool you need. No hunting through menus.

Helps you finish faster

Fewer clicks, fewer dead ends, more work actually completed.

Cuts training time for new employees

New hires get answers the moment they need them, so they're productive on day one instead of week three, and your managers stop repeating the same instructions.

Also included · Messenger

BusinessOS Messenger

Your team already has enough apps. Messenger is built right into BusinessOS, so staff can talk to each other without ever leaving the software they work in all day, and every message stays on your own network.

One-to-one conversations

Quick private messages between any two people on the team.

Team group chats

A dedicated space for each department, shift or location.

Company-wide announcements

Send one message and reach every screen in the business at once.

Instant notifications

Nothing gets missed, even when someone is on the other side of the building.

Real-time across every computer

Messages arrive the instant they're sent, on every connected machine.

Why it pays off

What you pay now, and what you'd pay instead

Most businesses rent six to eight tools that barely talk to each other. Here is that cost against one system you buy once and own.

Step 1 · What you pay today

Type in what you actually pay each month. Put 0 for anything you don't use.

No monthly stack. No per-tool fees. $995 once, and every month afterwards is money you keep instead of sending to seven different vendors.

How much could your business save?

This takes the $2,400/yr in subscriptions you entered in Step 1 and adds the value of the time your team gets back. Move the sliders to match your business.

Subscriptions are only part of it. The bigger cost is the time your team loses switching between tools and typing the same thing twice, which the estimate above already includes.

Default subscription prices are illustrative examples of common tool pricing, not quotes. Replace them with your own. Figures below are illustrative estimates. Time savings are the hours your team stops losing to switching tools and re-typing data; money savings value those hours at the pay you set, plus the monthly subscriptions BusinessOS replaces. Your actual savings depend on the tools you replace, your team size, and how your team works.

Good questions

Frequently asked

Is there business management software I can buy once instead of paying monthly?

Yes. BusinessOS by Legacy Builders is all-in-one small business management software sold as a one-time purchase: $995 once, with no subscription and no per-user fees. It runs locally on your own computers, so it's also offline business management software that keeps working without internet.

Is BusinessOS by Legacy Builders the same as other products called BusinessOS?

No. BusinessOS by Legacy Builders is made by Legacy Builders Systems LLC, a Florida company, and is sold only at legacybuildersos.com. It is not connected to other companies or apps that use a similar name.

Can I use it on my phone or tablet?

Yes. Install BusinessOS once on a Windows computer, your host. Then any phone or tablet, including iPhone, iPad and Android, opens it in its web browser while connected to your business Wi-Fi. There is nothing to install on the phone, and everyone sees the same clients, sales and schedules in real time. Just want to try it on one device? Use the web version.

Where is my data stored?

On your own computer. You install it on one machine, the host, and that is where your records live. Your other computers reach them over your own local network. Nothing is uploaded to us or to any cloud, ever.

Does it really work without internet?

Yes. Once installed, day-to-day work needs no internet, which suits shops, job sites and unreliable WiFi. Only the download, updates and optional extras like card payments need a connection. Your computers share data over your own local network.

What does the 30 day free trial include?

Everything. The trial is the full product with every feature unlocked for 30 days, not a limited demo. No credit card is required to start, and there's no compromise on functionality.

How much does it cost?

BusinessOS is $995, paid once. There is no subscription, no per-user charge and no monthly bill, and free updates are included. Start with the free 30-day trial, no card required. You can be certain it fits your business before you pay anything, and every license carries a 30-day money-back guarantee after purchase.

What kind of businesses is it for?

Almost any small or growing business, restaurants, salons, gyms, auto shops, cleaning and landscaping crews, retail stores, clinics, spas and more. A quick setup wizard tailors the software to your industry.

How do I get started?

Download it straight from this page, with no form and no account. Install it on one computer, and your 30 days start the first time you open it. Connecting the other computers takes minutes.

Can I get my money back if it is not right for us?

Yes. Every license is covered by a 30-day money-back guarantee. Email us within 30 days of your purchase and we refund the full license fee, no explanation needed. That is on top of the 30-day free trial, so you can run your business on BusinessOS for a month before paying anything, and still have a month afterwards to change your mind. See our Refund Policy.

Do I have to install it on every computer?

No. You install it on one computer, the host. Every other computer, phone and tablet in the building connects over the network you already have, with nothing to install.

What if I have more than one location?

One host serves one building, since connected computers share data over a single local network. Running more than one site? Email us your locations and computer count before you buy and we will tell you honestly what works.

Will it work with my accountant and QuickBooks?

BusinessOS replaces the stack rather than sitting alongside it, so there is no live sync with QuickBooks. Instead you get a clean handover: every report, invoice and receipt prints or saves as a PDF, and your full records export as a file. That is usually all an accountant needs.

What is the web version, and how is it different?

The Windows app is the full product: every feature, all your computers, phones and tablets connected to one shared system, offline use, and every record kept on your own machines. The web version opens in a browser with nothing to install, but it works on one device only and its data stays in that browser. It is a quick way to try BusinessOS or run a one-person business; choose the Windows app for a team.

What happens when the 30 day trial ends?

Nothing is deleted. Your records stay on your computer exactly as you left them. Entering your activation code unlocks the software again and everything you entered during the trial is right where it was.

What kind of support do I get, and how fast?

Email support, answered within 1 business day. Installation, setup and troubleshooting are included permanently, at no extra charge. Inside the software, the AI Assistant handles most day-to-day questions instantly.

Is my data safe if my computer is stolen or breaks?

BusinessOS backs itself up daily and keeps the last 30 restore points. Point it at an external drive or network folder and a copy lands there too, so your backup survives even if the computer doesn't. Lost a machine? Reinstall on any Windows PC, import the backup, and carry on. Nothing to repurchase, no account to recover.

Do I need to be good with computers to run this?

No. A setup wizard tailors it to your industry, a guided tour shows you around, and the built-in AI Assistant answers questions and takes you to the right screen. No manual, no IT team.

Are there any other fees, per user or otherwise?

None. $995 once covers your host computer and every machine that connects to it, including updates. Nothing recurring is ever set up, so there is nothing to cancel.

If the host computer fails, your business continues

BusinessOS backs itself up every day. Getting back up is three steps you can do yourself, the same day.

1Daily automatic backupsBusinessOS saves a restore point of every record each day by itself. Connect an external drive or network folder and it copies them there too.
2Reinstall on any computerAny Windows PC. Nothing to repurchase, no account to recover.
3Import it and carry onYou are back exactly where you stopped, on every connected computer.

Company, policies & support

Everything governing how BusinessOS is licensed, supported and maintained, together with details of the company responsible for it.

Trust & transparency

Policies, support and company information

The terms under which BusinessOS is licensed, supported and maintained, and the company responsible for it.

Published by Legacy Builders Systems LLC
Product version BusinessOS v2.7.1
Runs on Windows 10 & 11
Privacy Policy

Effective date: 28 August 2026. Last revised: 8 October 2026.

BusinessOS is published by Legacy Builders Systems LLC ("the Company", "we", "us"). This policy explains what information we collect through this website, what happens to the information you enter into the software, and the rights available to you under United States state privacy laws and, where applicable, the laws of the United Kingdom and the European Economic Area.

1. Data you enter into the BusinessOS software

All records created within BusinessOS — including client, invoice, payment, personnel, payroll, inventory, appointment and financial records — are stored on the single host computer on which you install the software, and are made available to the other computers, phones and tablets you connect to that host over your own local network. This data is not transmitted to the Company, is not held on Company servers, and is not accessible to the Company. The software operates without user accounts and without an authentication server.

Because we never hold a copy of your records, we cannot recover them. Uninstalling the software, replacing a device, or clearing its stored data without first exporting a backup will result in permanent loss of that data.

2. Multi-computer sharing over your local network

The software is installed on one host computer. Where you choose to connect additional computers, BusinessOS transmits your business records between the host and those computers over the local network you control, so that every connected computer, phone and tablet displays the same information. Phones and tablets connect through their web browser while on your local network; nothing is installed on them, and the same records are displayed from the host. This traffic remains on your own network and is not routed through the Company or any third party. You are responsible for the security of that network, including router configuration, network passwords, and the physical and account security of the host and of each connected computer. See our Multi-Computer & Local Network policy below for full detail.

2A. The web version

We also offer a browser-based web version of BusinessOS, opened from the “Launch Web Version” button. The web version works on one device only and does not connect to other devices. Records you enter in it are stored in that browser's local storage on that device; they are not sent to the Company. Clearing that browser's data, using private browsing, or changing browser or device will remove them, and we cannot recover them. Export a backup regularly if you use the web version. The web version is delivered from a third-party web host, which receives your IP address and standard browser information when the page loads.

3. Optional third-party integrations you may enable

BusinessOS can connect to third-party services that you separately choose to enable, including payment processors such as Stripe. When you enable such an integration, the data required for that transaction is transmitted directly from your computer to the provider you selected, under that provider's own terms and privacy policy, and an internet connection is required for that feature. The Company does not receive that data. If you enable no integrations, the software operates without any external network connection. See our Payment Processing policy below.

4. Information you submit through this website

You can download BusinessOS and use the free trial without giving us any personal information; there is no sign-up form and no account. We only receive personal information when you choose to contact us, for example by emailing us, sending a support request prepared by the website assistant, or asking to purchase a license. In that case we receive your email address and whatever you include in your message, such as your name, business name or telephone number. We use it only to respond to you, provide support, and process and keep a record of your license purchase.

We do not sell your personal information, and we do not share it for cross-context behavioural advertising. We do not use it for automated decision-making or profiling.

5. Categories of information and purposes

Under the California Consumer Privacy Act as amended, the categories of personal information we collect through this website are: identifiers (such as name, email address and telephone number, when you send them to us); commercial information (records of licenses purchased); and internet or network activity information (IP address and standard browser information received by the third-party services described below). We collect these for the business purposes of responding to your inquiry, providing support, processing purchases, and maintaining records of communications. We do not collect sensitive personal information through this website.

6. Third-party services used by this website

This website loads Google Fonts and an optional Google Translate component. Downloads of the Windows software are served by GitHub, and the web version is served by a third-party web host. In serving those requests, those providers may receive your IP address and standard browser information under their own privacy policies. These are website services only; the installed Windows software does not call them.

7. Cookies and tracking

We do not operate advertising trackers, advertising cookies, or analytics profiling on this website, and we do not respond differently to Global Privacy Control or Do Not Track signals because we do not engage in the tracking those signals are designed to limit. The installed software uses your device's local storage solely to retain your business records and settings on that device. This website may store a few small preference values in your browser, such as your chosen language. They stay in your browser, are not tracking identifiers, and are cleared when you clear your browser data. The web version stores your records in your browser as described in section 2A.

8. Retention

Emails and support requests are retained for as long as needed to respond to you and to maintain a record of the license relationship, and are deleted on request as described below. Records you enter into the software are retained by you, on your own equipment, for as long as you choose.

9. Security

We maintain reasonable administrative and technical safeguards for the limited inquiry information we hold. No method of transmission or storage is completely secure, and we cannot guarantee absolute security. Because your business records remain on your own equipment, the security of those records depends on the security of your devices and network.

10. Notification of a security incident

If we become aware of a breach affecting personal information we hold, we will notify affected individuals and any required regulators in accordance with applicable state breach notification laws, without unreasonable delay. Because we do not hold your business records, a compromise of your own device or network is outside our systems; we will assist you where we reasonably can, but the notification obligations arising from such an event rest with you as the controller of that data.

11. Your rights — United States

Depending on your state of residence, you may have the right to know what personal information we have collected about you, to obtain a copy of it, to correct inaccuracies, to request deletion, and to be free from discrimination for exercising those rights. Residents of California, Virginia, Colorado, Connecticut, Utah, Texas, Oregon, Montana, Delaware, Iowa, Nebraska, New Hampshire, New Jersey, Tennessee, Minnesota, Maryland, Indiana, Kentucky and Rhode Island, among others, have rights of this kind under their state privacy statutes. We do not sell personal information or use it for targeted advertising, so no opt-out of those activities is required. To exercise a right, contact us at the address in section 14. We will verify your request using the contact details you originally provided and respond within the period required by your state's law. You may use an authorised agent where your state's law permits.

12. Your rights — United Kingdom and European Economic Area

Where the UK GDPR or EU GDPR applies to you, our lawful basis for processing the information you send us is our legitimate interest in responding to a business inquiry you initiated, and, where you have given it, your consent to be contacted. You have the rights of access, rectification, erasure, restriction, portability and objection, the right to withdraw consent at any time, and the right to lodge a complaint with your supervisory authority. Information submitted through this website is transferred to and stored in the United States; where required, such transfers are made on the basis of the European Commission's Standard Contractual Clauses or an equivalent approved mechanism. The software itself transfers nothing internationally, because it does not transmit your records at all.

13. Children

BusinessOS is business software sold to businesses. It is not directed to children, and we do not knowingly collect personal information from anyone under 16 through this website. If you believe a child has provided us information, contact us and we will delete it.

14. Contact and changes

Privacy requests and questions: legacy.builders.systems@gmail.com. The Company is located in Miami, Florida, United States, and email is the fastest way to reach us; every inquiry receives a reply. We may update this policy; the revised version will be published on this page with an updated revision date, and material changes will be identified as such.

Terms of Use & Software License Agreement

Effective date: 28 August 2026. Last revised: 8 October 2026. These terms contain a binding arbitration clause and a class action waiver in section 15, and a limitation of liability in section 13. Please read them.

These terms form a binding agreement between you (and the business you represent) and Legacy Builders Systems LLC. By downloading, installing or using BusinessOS, or by using this website, you accept them. If you do not accept them, do not download, install or use the software.

1. Eligibility and authority

You must be at least 18 years old and legally able to enter into contracts. If you accept these terms on behalf of a business, you represent that you are authorised to bind that business, and "you" means that business.

2. License grant

Subject to these terms and to payment of the applicable license fee, the Company grants you a limited, non-exclusive, non-transferable, non-sublicensable license to install BusinessOS on one host computer and use it in the ordinary operation of your own business, together with the connection of the other computers, phones and tablets used in that same business at that same location, over your own local network. Phones and tablets connect through a web browser and do not receive their own installation. Use of the web version is licensed for one device. The license is acquired by a one-time purchase and is not a recurring subscription. The software is licensed, not sold; all rights not expressly granted are reserved.

3. Restrictions

You may not: resell, rent, lease, lend, sublicense, distribute or host the software as a service for third parties; copy the software except for a reasonable backup; modify, translate, adapt or create derivative works from it; reverse engineer, decompile or disassemble it, except to the extent that applicable law expressly permits despite this restriction; remove, obscure or alter any proprietary notice or branding; circumvent, disable or tamper with the trial period, activation, licensing or security features; or use the software to develop a competing product.

4. Trial

The 30-day trial provides the complete product with all features unlocked and requires no payment card. The trial period begins on first launch of the software on your device. On expiry the software enters a locked state and presents an activation screen; your data is not deleted and becomes accessible again on activation. One trial is permitted per business.

5. Fees, taxes and activation

License fees are those quoted to you in writing at the time of purchase. You are responsible for all sales, use, VAT, GST and similar taxes arising from your purchase, other than taxes on the Company's net income. Activation codes are issued to the purchasing business and may not be shared, published or transferred without our written consent.

6. Your data and your responsibilities

You retain all rights in the data you enter into the software. Because that data resides on your own equipment, you are solely responsible for: the security and physical control of each device and of any local network you connect them over; user access, passwords and permissions within your business; creating and retaining adequate backups; and ensuring your use of the software complies with all laws applicable to your business, including tax, payroll, wage-and-hour, employment, consumer protection, privacy and record-retention obligations.

7. Acceptable use

You may not use the software or this website to violate any law; to store or process data you have no right to hold; to infringe intellectual property or privacy rights; to transmit malware; to attempt unauthorised access to any system or network; or to interfere with the operation of the software for other licensees. See the Acceptable Use Policy below.

8. Third-party services and integrations

The Company makes a browser-based web version of BusinessOS available. These terms, the disclaimer of warranties and the limitation of liability apply to it in the same way as to the installed software. The web version runs on one device only, does not connect to other devices, and stores records in that browser on that device. Records there are lost if browser data is cleared or the device is changed, and the Company cannot recover them. Its page is delivered over the internet from a third-party host, and the web version may be changed or withdrawn at any time. Use the Windows software for records you need to share across devices or keep under your own backup routine.

9. Data locality: your records never reach the Company

BusinessOS is installed software that runs on equipment you own and control. All records you create in it — including client, patient, customer, employee, payroll, invoice, payment, inventory, appointment and financial records, and any files or notes you attach — are written to and stored on your host computer and are shared only with the other computers you connect to that host over your own local network.

The Company operates no server, cloud service, hosted database or backup facility that receives, stores, maintains, processes or transmits those records. We do not have credentials for your host computer, no remote access to it, and no copy of its contents. The software does not transmit your business records to the Company, and the Company cannot retrieve, read, restore, produce or delete them. Any backup, export or copy exists only where you place it.

The only information the Company receives is the information you deliberately send us: the details you send us when you contact us or purchase a license, the contents of emails you send us, and anything you voluntarily attach to a support request. If you choose to send us a file to help diagnose a problem, you are responsible for removing or masking sensitive information first.

Two exceptions arise from choices you make. First, any third-party service you enable inside the software, such as a payment processor, receives the data that service needs directly from your computer under that provider's own terms, and not through the Company. Second, if you use the web version, records you enter there are stored in that browser on that one device, as described in section 8, and you are responsible for backing them up.

Because of this architecture, the Company is not a custodian, processor, service provider or business associate of your records, and cannot perform obligations that depend on holding them, including responding to access, deletion or portability requests made to you, producing records in litigation or an audit, restoring data after a device failure, or providing breach notification for an incident affecting your equipment or network. Those obligations remain with you, and the security of your devices, network, user accounts and backups is your responsibility as set out in section 6.

10. Not professional advice

BusinessOS is a record-keeping and business operations tool. Reports, payroll figures, tax fields, and financial outputs it generates are for internal management purposes only and are not accounting, tax, legal, medical or other professional advice. You must have outputs reviewed by a suitably qualified professional before filing or otherwise relying on them. See the Regulated Industries and the Payroll, Tax & Financial Disclaimer policies below.

11. Intellectual property

The software, this website, and all associated text, design, graphics, code and branding are owned by the Company or its licensors and are protected by United States and international copyright, trademark and other laws. Feedback or suggestions you provide may be used by the Company without restriction or obligation to you.

12. Disclaimer of warranties

THE SOFTWARE AND THIS WEBSITE ARE PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTY OF ANY KIND. TO THE FULLEST EXTENT PERMITTED BY LAW, THE COMPANY DISCLAIMS ALL WARRANTIES, EXPRESS, IMPLIED OR STATUTORY, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, QUIET ENJOYMENT, ACCURACY AND NON-INFRINGEMENT. The Company does not warrant that the software will be uninterrupted, error-free, or free of harmful components, that defects will be corrected, or that it will meet your requirements or achieve any particular result. No advice or information, whether oral or written, creates any warranty not expressly stated here. Some jurisdictions do not allow the exclusion of certain warranties, so parts of this section may not apply to you.

13. Limitation of liability

TO THE FULLEST EXTENT PERMITTED BY LAW, THE COMPANY AND ITS MEMBERS, OFFICERS AND AGENTS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, GOODWILL, BUSINESS INTERRUPTION, OR LOSS, CORRUPTION OR INABILITY TO RECOVER DATA, ARISING OUT OF OR RELATING TO THE SOFTWARE, THIS WEBSITE, OR THESE TERMS, ON ANY THEORY OF LIABILITY, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. THE COMPANY'S TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS WILL NOT EXCEED THE AMOUNT YOU ACTUALLY PAID THE COMPANY FOR THE LICENSE GIVING RISE TO THE CLAIM. These limitations apply even if a limited remedy fails of its essential purpose, and form an essential basis of the bargain between us. Nothing in these terms excludes liability that cannot lawfully be excluded, including liability for fraud or for death or personal injury caused by negligence. Some jurisdictions do not allow certain limitations, so parts of this section may not apply to you.

14. Indemnity

You will indemnify and hold harmless the Company and its members, officers and agents from any third-party claim, demand, loss, liability or expense (including reasonable legal fees) arising out of your use of the software or website, your data, your breach of these terms, or your violation of any law or third-party right.

15. Dispute resolution, arbitration and class action waiver

Informal resolution first. Before starting any proceeding, you agree to contact us at the address below with a written description of the dispute and to allow 30 days for good-faith resolution.

Binding arbitration. If the dispute is not resolved, any dispute arising out of or relating to these terms, the software or this website will be resolved by final and binding individual arbitration administered by the American Arbitration Association under its Consumer Arbitration Rules or Commercial Arbitration Rules as applicable, before a single arbitrator, seated in Miami-Dade County, Florida or, at your election, by telephone, video or written submission. The Federal Arbitration Act governs the interpretation and enforcement of this section.

Class action and jury waiver. DISPUTES WILL BE ARBITRATED ONLY ON AN INDIVIDUAL BASIS. YOU AND THE COMPANY WAIVE THE RIGHT TO A JURY TRIAL AND THE RIGHT TO PARTICIPATE IN A CLASS, COLLECTIVE, CONSOLIDATED OR REPRESENTATIVE ACTION. If this waiver is found unenforceable as to a particular claim, that claim will proceed in court and the remainder will remain in arbitration.

Exceptions. Either party may bring an individual claim in small claims court, and either party may seek injunctive relief in court for infringement or misuse of intellectual property.

Your right to opt out. You may reject this arbitration agreement by sending written notice to legacy.builders.systems@gmail.com with your name, business name and a clear statement that you opt out, within 30 days of first accepting these terms. Opting out does not affect any other part of these terms.

15A. Time limit for claims

To the extent permitted by law, any claim arising out of or relating to these terms, the software or this website must be brought within one (1) year after the claim arises; otherwise it is permanently barred.

16. Governing law and venue

These terms are governed by the laws of the State of Florida and applicable United States federal law, without regard to conflict-of-law rules. The United Nations Convention on Contracts for the International Sale of Goods does not apply. Subject to section 15, the state and federal courts located in Miami-Dade County, Florida have exclusive jurisdiction, and both parties consent to that jurisdiction and venue. If you are a consumer resident in the United Kingdom or the European Economic Area, nothing here deprives you of the protection of mandatory provisions of the law of your country of residence.

17. Term, suspension and termination

The license continues until terminated. It terminates automatically if you materially breach these terms, and the Company may terminate or suspend a license used in breach on written notice. On termination you must stop using and remove the software; you may export your data first. Sections 6 and 9 to 16 survive termination.

18. Changes to these terms

The Company may amend these terms and will publish the revised version here with an updated revision date. Material changes take effect 30 days after publication, and your continued use after that date constitutes acceptance. Changes do not apply retroactively to a dispute of which we had notice before publication.

19. General

Force majeure: neither party is liable for delay or failure caused by events beyond its reasonable control. Assignment: you may not assign these terms without our written consent; we may assign them in connection with a merger or sale of assets. Severability: if a provision is held unenforceable, it is modified to the minimum extent necessary and the rest remains in force. No waiver: failure to enforce a provision is not a waiver of it. Entire agreement: these terms, together with the other policies published on this page, are the entire agreement between us regarding the software and supersede all prior discussions. Notices: notices to the Company must be sent by email to legacy.builders.systems@gmail.com. The Company is located in Miami, Florida, United States. Electronic agreement: you consent to contract electronically under the federal E-SIGN Act, and agree that your acceptance and our electronic records satisfy any requirement of a signed writing. Headings are for convenience only.

Acceptable Use Policy

This policy applies to the software, this website, and any support channel we operate. It exists to keep the product lawful and usable for everyone.

You may not

Use BusinessOS to conduct or facilitate unlawful activity; store, process or transmit data you have no lawful right to hold; infringe the intellectual property, privacy or publicity rights of any person; upload or transmit malware or any harmful code; probe, scan or attempt unauthorised access to any system, account or network, whether ours or a third party's; circumvent licensing, activation or trial controls, or assist another person in doing so; use the software to send unlawful marketing, including calls, texts, faxes or email sent in breach of the Telephone Consumer Protection Act or the CAN-SPAM Act; misrepresent the software as your own product or resell it without written authorisation; or use the built-in messaging features to harass, threaten, defame or unlawfully discriminate against any person.

Your workplace obligations

If you enable the built-in messaging features for your employees, you are the operator of that communication system. You are responsible for setting your own workplace communications and monitoring policy, for informing your employees of it, and for complying with the employment, privacy, wiretap and electronic-communications laws of every state in which your staff work, several of which require notice or consent before employee communications are monitored or retained.

Enforcement

We may suspend or terminate a license used in violation of this policy, and may report unlawful activity to the appropriate authorities. Where practical and lawful we will contact you first.

Payment Processing & Card Data

BusinessOS can connect to third-party payment providers, including Stripe, through their published interfaces, where you choose to enable that feature.

How card data is handled

BusinessOS does not store, and is not designed to store, full payment card numbers, magnetic-stripe data, card verification codes or PINs. Where you enable a payment integration, card details are handled by the payment provider you selected, under that provider's own security program and terms. BusinessOS records the outcome of the transaction — such as amount, date, method and the reference returned by the provider — for your bookkeeping.

Your merchant obligations

Your relationship with a payment provider is a separate agreement between you and that provider. You are responsible for entering into it, for the fees and chargeback terms it contains, for the accuracy of the payments you take, and for your own obligations as a merchant under the Payment Card Industry Data Security Standard, including the annual validation your acquirer requires of you. You are also responsible for keeping your own API keys and provider credentials secret, and for revoking them if a device is lost or an employee leaves.

Internet connection

Payment integrations and other third-party connections require an internet connection while they are in use. All other functions of BusinessOS continue to operate offline.

Refunds, chargebacks and disputes

Disputes about a payment your customer made to you are between you, your customer and your payment provider. The Company is not a party to those transactions, does not hold funds, and cannot reverse, release or adjust them.

Regulated Industries & Compliance Responsibilities

BusinessOS is general-purpose business software. It is not certified, validated or warranted for use in any regulated capacity, and the Company does not act as your compliance provider. Where your business is regulated, you remain responsible for meeting the requirements that apply to it.

Health, medical and wellness businesses

BusinessOS is not a HIPAA-compliant system of record, and the Company does not act as a Business Associate or enter into Business Associate Agreements. If you are a covered entity or business associate under the Health Insurance Portability and Accountability Act, you must not enter protected health information into BusinessOS unless you have independently satisfied yourself that your own configuration, device security, network security and safeguards meet the Privacy, Security and Breach Notification Rules, and you accept sole responsibility for that determination. As set out in section 9 of the Terms of Use, the Company operates no server that receives or stores anything you enter into the software, has no access to it, and therefore does not create, receive, maintain or transmit protected health information on your behalf. The same applies to state health-privacy statutes, including the Washington My Health My Data Act and comparable laws, and to any consumer health data those laws cover.

Payroll, employment and wage records

Payroll, scheduling, time-tracking and personnel features are recording tools. You are responsible for compliance with the Fair Labor Standards Act, state wage-and-hour and pay-transparency laws, overtime and break rules, tip-credit rules, final-pay timing, employee classification, recordkeeping retention periods, and all federal, state and local tax withholding, deposit and filing obligations. The software does not file returns, remit taxes, or determine classification for you.

Financial records and accounting

Outputs are management reports, not audited financial statements, and are not prepared in accordance with GAAP unless you make them so. You are responsible for the accuracy of your books and for any filing made from them.

Biometric, background and sensitive personnel data

If you use any feature to record biometric identifiers, you are responsible for compliance with the Illinois Biometric Information Privacy Act and comparable state statutes, which generally require written notice and consent before collection. Background-check information is subject to the Fair Credit Reporting Act and state equivalents.

Consumer-facing operations

You are responsible for compliance with the FTC Act and state consumer protection statutes in how you advertise and price; with gift card rules under the CARD Act and state escheat and expiry laws; with electronic receipt and FACTA card-truncation requirements; with the Americans with Disabilities Act as it applies to your own premises and customer-facing materials; and with any licensing regime specific to your trade, including alcohol, cannabis, firearms, childcare, cosmetology, automotive repair, food service and professional licensure. Some categories of business are subject to restrictions that make this software unsuitable; it is your responsibility to determine that before relying on it.

Data you hold about other people

Where you enter personal information about your own clients or employees, you are the controller or business with respect to that data under applicable privacy law. The obligations to give notice, honour rights requests, and notify in the event of a breach rest with you, not with the Company, because the Company never receives that data.

No certification

The Company makes no representation that BusinessOS is compliant with HIPAA, PCI DSS, SOC 2, ISO 27001, GAAP, the FDA's regulations, or any other standard, framework or audit regime.

Customer Reviews & Testimonials

Reviews and testimonials shown on this website are the personal opinions and experiences of individual BusinessOS customers, published with their permission. They are not statements by Legacy Builders Systems LLC about how the software will perform for any other business.

No guarantee of results

Experiences described in a review are specific to that customer's business, team, industry and way of working. They are not a promise, warranty or guarantee that you will obtain the same or similar results, savings, time recovered or revenue. Your results will differ.

How reviews are collected

Reviewers are BusinessOS customers. Reviewers are not paid for their reviews and receive no discount, commission or other compensation in exchange for them. Where a customer approves wording that we drafted from their feedback, it is published only with that customer's consent. Names may be shortened for privacy.

Savings figures and estimates

Any figures shown in a review, and any amounts produced by the savings estimator on this website, are illustrative estimates based on the inputs provided. They are not quotes, projections or guarantees of financial outcome.

Questions or corrections

If you believe a review on this website is inaccurate, or if you are a reviewer who wishes to amend or withdraw your review, contact us and we will correct or remove it promptly.

Payroll, Tax & Financial Disclaimer

Legacy Builders Systems LLC is a software publisher. It is not a certified public accounting firm, a payroll service bureau, a tax preparer, a registered agent, a law firm, or a financial adviser, and nothing produced by BusinessOS constitutes accounting, tax, legal or financial advice.

What the software does and does not do

BusinessOS calculates from the figures and rates you enter and the settings you choose. It does not maintain statutory tax tables on your behalf, does not file federal, state or local returns, does not remit withholding or deposits, does not generate or transmit W-2, 1099, 940 or 941 filings to any authority, and does not monitor changes in law that may affect your obligations.

Your responsibility

You are responsible for the accuracy of every figure entered, for the correctness of the rates and settings you configure, and for having a qualified accountant or tax professional review any output before it is filed, submitted, paid or relied upon. Any penalty, interest, assessment or liability arising from a filing or payment is your responsibility.

No guarantee of results

Any savings figures, time savings, calculators or comparisons shown on this website are illustrative estimates based on the assumptions stated, offered for general comparison only. They are not a promise, projection or guarantee of the results your business will achieve, which depend on factors outside the Company's control.

Communications & Contact Consent

When you submit the trial request form, you are asking us to contact you about BusinessOS, and you consent to our doing so at the email address and telephone number you provide. Both fields are required on that form, and the notice beside the submit button states this before you send it.

Calls and text messages

By submitting the trial request form you agree that Legacy Builders Systems LLC may call or send text messages to the number you provide regarding your trial, your pricing and your inquiry, including by automated means where used. We do not send automated marketing campaigns to that number without separate express written consent obtained at the time. Consent to marketing calls or texts is not a condition of purchasing anything. Message and data rates may apply, and message frequency varies. Reply STOP to any text message to opt out, or HELP for assistance. You may also withdraw consent at any time by emailing us.

Email

We send email in connection with your inquiry, your trial, your license, and occasional product notices. Every commercial message identifies us, states our postal address, and contains a working unsubscribe mechanism honored promptly, in accordance with the CAN-SPAM Act. Transactional messages about a license you hold are not marketing and may continue after you unsubscribe from marketing.

Recording

We do not record telephone calls. If that changes, we will obtain the consent required by the laws of your state before doing so.

Accessibility Statement

Legacy Builders Systems LLC intends this website and BusinessOS to be usable by as many people as possible, including people who use assistive technology.

Our approach

We aim to meet the Web Content Accessibility Guidelines version 2.1 at Level AA as a working standard, and we take it into account when we design new features. We do not claim full conformance, and we know some areas fall short of it.

Feedback and assistance

If any part of this website or the software presents a barrier to you, please write to legacy.builders.systems@gmail.com describing the page or screen, the difficulty, and the assistive technology you use. We will respond and will work with you to provide the information or function you need in an alternative accessible format while we address the underlying issue.

International Use, Export Control & Sanctions

BusinessOS is published from the United States and is made available to customers in other countries.

Local law is your responsibility

If you use the software outside the United States, you do so on your own initiative and are responsible for compliance with the laws of your jurisdiction, including its tax, invoicing, employment, consumer protection and data protection requirements. Features intended for United States practice, including tax fields and payroll formats, may not correspond to the requirements of your country. Nothing on this website is an offer in a jurisdiction where such an offer would be unlawful.

Export control and sanctions

The software is subject to United States export control laws, including the Export Administration Regulations, and to sanctions administered by the Office of Foreign Assets Control. You represent that you are not located in, ordinarily resident in, or a national of any country or region subject to comprehensive United States sanctions, that you are not listed on any United States government list of prohibited or restricted parties, and that you will not export, re-export or make the software available in violation of those laws.

Language

The translation feature on this website is an automated convenience provided by a third party. The English version of these policies is the authoritative one; in the event of a discrepancy, the English text governs.

Intellectual Property & Copyright Complaints

BusinessOS, the BusinessOS name and crest, this website, and all associated design, text, graphics and code are the property of Legacy Builders Systems LLC or its licensors, and are protected by copyright, trademark and other laws. No license to any trademark is granted by these terms.

Third-party components

The software and website incorporate third-party components under their respective open-source or commercial licenses. Those licenses continue to govern those components, and nothing in our terms limits any right you have under them.

Copyright complaints

If you believe material published on this website infringes your copyright, send a notice under the Digital Millennium Copyright Act to legacy.builders.systems@gmail.com, identifying the copyrighted work, identifying the material and its location, providing your contact details, and including statements that you have a good-faith belief the use is unauthorised and that the information in the notice is accurate, made under penalty of perjury, with your physical or electronic signature. We will respond in accordance with the Act, and we terminate the licenses of repeat infringers.

Refund & Cancellation Policy
30-day money-back guarantee

If BusinessOS is not right for your business, you may request a full refund of the license fee within 30 days of the date of purchase. No explanation is required.

To request a refund, email legacy.builders.systems@gmail.com from the email address used at purchase, stating your business name and order date. Requests received within the 30-day period are approved and refunded to the original payment method, ordinarily within five to ten business days, subject to your bank's processing times. Any sales tax collected is refunded with the license fee. Payment processing fees are borne by us and are not deducted from your refund.

On refund, the license terminates and the activation code is deactivated. You agree to stop using BusinessOS and to remove it from your computers. Your business records remain on your own computers and are yours; we hold no copy and remove nothing.

The guarantee applies once per business to the purchase of a BusinessOS license. Requests received after 30 days from the date of purchase are outside the guarantee, except where a refund is required by the law of your jurisdiction, in which case that law prevails over this policy.

The free trial

Before any payment, you receive the complete product with every feature unlocked for a full 30 days, without a payment card. The guarantee above is in addition to that trial, so you may evaluate BusinessOS for 30 days free, and still have 30 days after purchase to change your mind.

Cancellation

There is no subscription, so there is nothing to cancel and no recurring charge is ever set up. If you decide during the trial that BusinessOS is not right for your business, simply stop using it; no charge is incurred and no notice is required. Requests to remove any details you have sent us from our records are actioned on receipt.

Technical remedy

If the software fails to operate correctly on your system after purchase, we will work with you toward a resolution. Contact legacy.builders.systems@gmail.com with your business name and a description of the issue. Where we cannot resolve a defect that prevents the software from functioning substantially as described, we will refund the license fee, whether or not the 30-day guarantee period has passed.

Chargebacks

If you believe a charge is incorrect, contact us first; a refund within the guarantee period is quicker for both of us. Initiating a chargeback without contacting us may result in termination of the license.

Support Information

Technical support for BusinessOS is provided by Legacy Builders Systems LLC by email.

Contact channels

Support enquiries should be directed to legacy.builders.systems@gmail.com. The support assistant on this page additionally answers frequently asked questions immediately and can submit a support request on your behalf.

Information required

To enable resolution at first response, please state your business name, the module or screen in use, the behaviour you expected, the behaviour you observed, and the operating system and version you are running.

Scope of support

Support covers installation and configuration of the host, guidance on module functionality, industry configuration, connecting your other computers, phones and tablets to the host over your local network, the web version, data import and export, activation, and investigation of defects. Support does not extend to bookkeeping, taxation or legal advice; to the configuration or repair of your own network hardware, router or firewall; to third-party payment provider accounts; or to recovery of data from a device for which no backup was exported.

Response times

We aim to reply to support email within 1 business day. No specific resolution time is guaranteed, and support is provided during ordinary business hours.

Trial Expiration

The BusinessOS trial provides the complete product, with all features unlocked, for 30 days. No payment card is required to begin.

Calculation of the trial period

The trial period begins automatically on first launch of the software on your device, not on the date you downloaded it. These trial terms describe the Windows software; the web version may have its own usage limits shown within it. A countdown indicator inside the application shows the time remaining, so the expiry date is known in advance.

Effect of expiry

At the end of the 30 days, BusinessOS enters a locked state and presents an activation screen. Your data is not deleted. All records remain stored on your device and become accessible again immediately on activation.

Continuation of use

To continue, contact the Company to purchase a license, and an activation code will be issued to unlock the software permanently on that device. As a precaution, export a backup before the trial expires.

Backup & Data Export

Because your data resides solely on your own equipment, responsibility for creating and retaining backups rests with you.

Automatic backups

BusinessOS creates a restore point automatically every day (daily is the default; you can change it in Settings) and keeps the most recent 30. For protection against losing the host computer itself, connect a backup folder on an external drive or network location in Settings, and backup files are written there as well.

Exporting a backup

In BusinessOS, open Settings and select Export JSON Backup. The software generates a single dated file, businessos-backup-YYYY-MM-DD.json, containing all records held in the system. Keep this file somewhere secure, such as an external drive or a storage service of your choosing.

Restoring a backup

From the same Settings screen, select Import JSON Backup and choose a previously exported file. Use the same procedure to move a business to a replacement computer.

Multi-computer setups

Your records live on the host computer, so that is where backups matter most; export from the host to capture everything. Connecting computers is not itself a backup, because there is only one set of records: anything deleted from a connected computer is deleted for everyone. Keep exported backups regardless of how many machines you run, and store them somewhere other than the host.

Reports and printed records

Individual reports, invoices and receipts may also be printed or saved as PDF from their own screens, which helps when providing records to an accountant.

Recommended practice

Keep daily automatic backups turned on (the default) and connect a backup folder on an external drive or network location, so copies are stored off the host computer. Also export a backup before changing devices, reinstalling, or updating. Because the Company never receives a copy of your data, it cannot restore anything if a device is lost and no backup exists.

Implementation & Onboarding

BusinessOS is designed to be deployed the day you receive it. No server provisioning is required and no IT implementation project is necessary.

1. Install on one computer

Download the Windows version and run the installer on the single computer that will act as your host. On first launch, a short configuration screen records your business details and industry, which tailors the software to how you operate. This can be changed later in Settings. Choose a machine that stays switched on during business hours, as connected computers reach their data through it.

2. Connect your other computers

Your remaining computers, and any phones and tablets, connect to the host over your local network, following the setup guidance shown in the application; computers do not need their own installation, and phones and tablets open BusinessOS in their web browser. All connected computers, phones and tablets must be on the same local network as the host.

3. Guided product tour

A built-in walkthrough introduces the dashboard and the main modules in sequence. It can be reopened at any time from System Tour in the sidebar, which is useful when onboarding new staff.

4. Bring in your existing records

Client, personnel, product and service records may be entered directly, or a JSON backup may be imported when migrating from another device. Sample data is available in Settings so you can explore before entering live records.

Assistance

If you need help at any stage, contact legacy.builders.systems@gmail.com.

Product Version

The current release is BusinessOS v2.7.1. The version installed on a given computer can be confirmed inside the software under Settings → Version.

Because BusinessOS runs entirely on your own equipment, updates are issued as a replacement installer rather than deployed automatically, leaving the timing of any update to you. As the software is installed only on the host, an update is applied once, on that computer, and connected machines pick it up automatically. Export a backup before updating.

Supported Operating Systems & Requirements

BusinessOS installs and runs on your own computer and operates offline for its core functions.

The host computer

BusinessOS is installed on one computer, which acts as the host for the business. The host may run Windows 10 or Windows 11 (64-bit). Your other computers connect to the host and do not require their own installation. Choose a host that remains switched on and connected during business hours, since connected computers reach their data through it.

Connected computers

Other Windows computers on the same local network connect to the host without their own installation. Phones and tablets (such as iPhone, iPad and Android devices) connect through a current web browser while on the same local network. A full-size display is recommended for heavy daily data entry.

Hardware

Any current desktop or laptop computer meeting the ordinary requirements of the operating systems above. Where a larger number of computers connect at once, a host with more memory will perform better.

Network requirements

No internet connection is required for routine operation. An internet connection is required to download the software, to receive updates, and while any optional third-party integration, such as a payment provider, is in use. All connected computers, phones and tablets must be on the same local network as the host, and that network must permit local connections between them; some managed, guest or public networks block this by default.

Web version

The web version runs in a current web browser on one device and needs an internet connection to open. It does not connect to the host or to other devices, and its records stay in that browser.

Installation permissions

Installing on the host may require administrator rights on that computer and, on some networks, an allowance in the firewall so connected computers can reach the host. Your IT provider, where you use one, can apply this in a few minutes.

Multi-Computer & Local Network Data Sharing

BusinessOS can connect several computers in the same business so they display and update the same records in real time.

How it works

The software is installed on a single host computer, which holds your business records. Your other computers, phones and tablets connect to that host over the local network you already operate, and do not need their own installation; phones and tablets use their web browser. That traffic stays within your own network. It is not routed through the Company, is not stored on any Company server, and is not accessible to the Company or to any third party we engage.

Choosing and protecting the host

Because your records reside on the host, that computer requires particular care. It should remain switched on and connected during business hours, should be physically secure, should have disk encryption and current operating system updates, and should be included in your backup routine. If the host is lost, damaged or replaced, your records are recovered from your exported backup, not from the Company, which never holds a copy.

What you are responsible for

You control the network, so you control the security of what travels on it. You are responsible for: securing your router and wireless network with a strong password and current firmware; restricting network access to equipment and people you trust; the security, availability and backup of the host computer; keeping each connected computer's, phone's and tablet's operating system, screen lock, user accounts and encryption in good order; removing a device from the connection when it leaves your business or an employee departs; and configuring user permissions inside BusinessOS so staff see only what their role requires. Connecting computers over an untrusted, public or shared network is not recommended.

Availability

Real-time sharing depends on your own network and on the host. If the host is switched off, asleep or disconnected, connected computers cannot reach the data until it is available again. If a connected computer loses its connection it will not receive updates until it reconnects. The Company does not warrant uninterrupted availability, because the host and the network it depends on are yours.

Not a backup

Connecting computers is not a backup. There is one set of records, held on the host, and a deletion made from any connected computer removes it for everyone. Export regular backups from the host as described in the Backup policy.

Artificial Intelligence Disclosure

Legacy Builders Systems LLC believes customers are entitled to understand where artificial intelligence sits in the software they depend on. This disclosure covers both the product and how it was built.

The BusinessOS Assistant runs entirely on your computer

The built-in assistant operates wholly on your own device and offline. It does not transmit your questions, your business records, or any other data to the Company, to any artificial intelligence provider, or to any other external service. No client, invoice, personnel, payroll or financial record is sent anywhere, and none of your data is used to train any model, by us or by anyone else.

What the assistant does

The assistant answers questions about the software's features, guides you through tasks step by step, and navigates you to the relevant screen. You are interacting with software, not with a human being.

Limits of the assistant

The assistant provides guidance on using BusinessOS. It does not give accounting, tax, legal, medical, employment or financial advice, and its answers are not a substitute for professional judgment. Like any automated system it may be incomplete or mistaken; where an answer affects a filing, a payment or a legal obligation, verify it. The assistant does not make decisions about people, and is not used for hiring, lending, insurance, housing, or any other consequential decision.

Development of the product

We also disclose that portions of BusinessOS were developed with the assistance of artificial intelligence tools, used alongside conventional development tools to author and refine parts of the source code, interface and written content. Product direction, design decisions and final approval remain the responsibility of Legacy Builders Systems LLC, all released functionality is reviewed and tested by us before distribution, and we accept full responsibility for the finished product regardless of the tools used to create it.

Website support assistant

The support assistant on this website is not an artificial intelligence model. It answers from a fixed set of written responses contained in this page, works without a network connection, and transmits nothing unless you choose to submit a support request.

About the Company

BusinessOS is developed and published by Legacy Builders Systems LLC, a limited liability company registered in the State of Florida and located in Miami, Florida, United States.

The Company develops business software that customers own outright and run on their own hardware, rather than software leased on a recurring basis from a cloud provider. That principle governs our product decisions: your records stay on your equipment, there is no account you can be locked out of, and there is no subscription to cancel.
